The Gradle failure may have been because of AndroidX incompatibilities in this Flutter app. See https://flutter.dev/docs/development/packages-and-plugins/androidx-compatibility for more information on the problem and how to fix it.
Gradle task assembleDebug failed with exit code 1 Exited (sigterm)
回答1:
First make sure that all your packages in the pubspec.yaml are of the latest version. Then open the android project of your flutter app with android studio, select Refactor->Migrate to Androidx(make sure that you are doing that that from the android project and not from the flutter one). Wait until android studio finishes migrating your project, rebuild your project. Hope it helps!

Thanks for your suggestion,
I've fixed it by doing these steps : 1. Try adding this line In your Project folder > android > app > build.gradle, add the following Line in
multiDexEnabled trueinside defaultConfig
Then upgrade gradle dependency in the android/build.gradle file: classpath 'com.android.tools.build:gradle:3.3.1' (previously on version 3.2.1)
Run flutter clean and rebuild your project

Create a new flutter project and move existing code to it: flutter migration
